Let's all keep in mind that I put an SPE 40cc in mine and it's just starting to break in. I'm sure that with a 3MM, DA, or DL50 it would totally out perform the 40. I just put a 3MM 53CC in a 16 pound 10 ounce WH Edge and it will outperform the Cap with the 40 hands down. In fact, until recently the 160 outperformed the 40. I only just got to run the 20X8 Xoar due to the long break-in time on these engines (3 gallons of gas). No question the 160 flies this plane like a dream but if I have to choose between $20.00 a gallon and $3.00, I'm going with gas. My next move will be to replace the 40 with a 50. BTW, welcome back Jeff!! Haven't seen ya on here lately. Hope you're done dodging twisters.
